✔ 最佳答案
-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8

-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8

-13 + (+12) - (-5/8)
= -13 + 12 + 5/8
= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8
答案是負8分之3。

(-13)+12-(-5/8)
=(-1)+(5/8)
=(3/8)
所以答案是3/8(八分之三)。

對不起,答案有錯誤!(-13)+12-(-5/8)=(-1)+(5/8)=(-3/8)所以答案是-3/8(負八分之三)才對。

               5
(-13)+(+12)-(- - )
               8


         5
= -13+12+ -----
         8

   3
= - -----  or - 0.375
   8

( - 13 ) + ( + 12 ) - ( - 5/8 )
= - 13 + 12 + ( 5/8 )
= - 1 + ( 5/8 )
= ( - 1 * 8 + 5 ) / 8
= ( - 8 + 5 ) / 8
= - 3 / 8
2006-12-31 10:57 pm
= -13+12+5/8
= -1+5/8
= -8/8+5/8
= -3/8

= 12 - 13 + 5/8
= -1 + 5/8
= -8/8 + 5/8
= (5-8)/8
= -3/8
